UltraBoost Mid 'Prototype'

adidas taps into their vault of silhouettes that never made it into production with the UltraBoost Mid Prototype. A precursor to the UltraBoost Mid, the shoe features a vibrant Solar Yellow Primeknit construction on a mid-top design, with a High Res Blue ribbed collar, white Three-Stripes branding and mismatched navy/grey overlays. An external heel counter increases stability, while the full-length Boost midsole delivers cushioning.
